BED-BOTTOM.

Specification of Letters Patent.

Patented Nov.11, 1919.

Application filed October 21, 1918, Serial No. 259,121. Renewed August9, 1919. Serial No. 316,491.

To all whom it may concern:

Be it known that I, JOHN M. MGCLAIN, a citizen of the United States,residing at Spokane, in the county of Spokane and State of Washington,have invented certain new and useful Improvements in Bed-Bottoms, ofwhich the following is a specification.

The present invention relates to improvements in bed bottoms,particularly of the slat and spring type, and the bed bottom which isthe subject matter of the invention is designed particularly with theview of providing a comparatively inexpensive, but effective, resilient,and durable support of this type which is well adapted for the requiredflexibility, yet in possession of suflicient rigidity to support theweight required without sagging or without undue depress1on.

The invention consists essentially in certain novel combinations andarrangements involving the parallel, longitudinal slats and theirsupporting cords or cables, and particularly in the manner of combiningthese slats and cords with the bottom frame.

In the accompanying drawings one complete example of the physicalembodiment of the invention is illustrated, combined and arrangedaccording to the best mode so far devised for the practical applicationof the principles of the invention.

Figure 1 is a top plan view of a bed bottom of the slat and spring typeembodying the novel features of the present invention.

Fig.2 is a longitudinal sectional view at line AA of Fig. 1.

Fig. 3 is an enlarged view of one of the slats, showing also theindependent and indlividual cable or wire for suspending each s at.

Fig. 4 is an enlarged transverse sectional view of one of the end barsof the bottom frame, showing details of construction.

In carrying out the principles of the invention and physically embodyingthe same in actual practice, a rectangular frame of suitable size isutilized, composed essentially of the two end bars 1 and 2 and the sidebars 3 and 4, all preferably of properly prepared wood, and the two endbars which might be termed the head and foot bars of the frame, are eachprovided with beveled or inclined upper faces 5, 5, to eliminate sharpcorners or edges and to allow for required movement of the supporting orsuspending members of the bed bottom, while at 6, 6, the outer curvedfaces of these bars are grooved, for a purpose to be described. Thesupporting medium of the bed bottom consists in a series of parallelslats 7, longitudinally arranged with relation to the bed, andpreferably of wood of proper thickness, or thinness, to render themsomewhat resilient to provide a flexible bottom. Each slat isindependently and individually supported between the two end barsthrough the medium of a cable or wire 8, which at 9, 9, is looped orbent about the end bars and passed loosely through the eyes or staples10, 10 in the bottom of the slat. Each slat has two loops 9 at each end,and beneath each slat the cables or wires are stretched along each sideof the slat between the eyes or staples so that the slat is stable andpresents a well sustained and supported element in the series ofparallel members. The supporting wires or cables pass loosely throughthe eyes of the staples so that the slats may be adjusted,longitudinally of the bed, and the ends of each cable are joined by acoiled spring as 11. Each cable is thus capable of movement throughoutits length, and to prevent wear by the loops 9 around the curved facesof the end bars, friction rods, of metal, as 12, 12 are retained in thegrooves 6, before referred to, to take up wear and prevent the wires orcables cutting into the wood from wear.

Preferably the slats in the series are joined or bound together by apair of wires 13, which binding cords or wires are woven about theslats, to retain them loosely, but at the same time preventdisplacement. The inclined faces 5 on the end bars, it will be apparent,permit depression of the upper strands of the supporting cables or wireswithout undesirable contact with a sharp corner or edge, thus allowingfor suflicient depression of the wire and at the same time providing asomewhat broad supporting face for the wire, in addition to the flathorizontal top surface of the end bars.

Claim- The combination with a supporting frame including the end barshaving inwardly and downwardly beveled upper faces and fricbers, aspring connecting the ends of each tion members at their outer faces, ofa series Wire, and said Wires passed loosely through of parallel slatsloosely Woven together and the staples to permit relative movement be 10provided With staples at their under faces, tween the slat and Wire.

supporting Wires for each slat, each said In testimony whereof I afiiXmy signature.

Wire having end loops about the end bars and frictionally engaging thefriction mem- JOHN M. MGCLAIN.
